Here’s one way to perform random acts of greenness. How often do we pass small and large bits of garbage or recycling when we are walking in our neighborhoods, but, for practical reasons, don’t act on our impulse to be good citizens. If we simply carried a rolled-up plastic bag with us, we could do a good deed and clean up Swarthmore without going out of our way. I got this idea after observing a neighbor do the same, while walking her dog. It was an “aha” moment for me.
